Features & Benefits

Ideal for:

• Cold waterproofing masonry or concrete poured over bare ground
• Waterproofing flat or curved surfaces on structures below ground level, such as man-made tunnels and underpasses
• Waterproofing horizontal concrete structures below screeds isolated with PE sheets (in such cases we recommend applying Mapelastic on the screed before installing flooring to protect the screed)

Surface Preparation

• The surface to be treated must be sound and perfectly clean
• Horizontal surfaces (which are then buried or remain below screed level) must have a slope of at least 1% so that water can run off towards the sides or towards drainage points
• Remove cement laitance, loose and crumbling parts and all traces of dust, grease, oil and form-release compounds. Before applying Plastimul on masonry in general (bricks, vibro-compressed concrete blocks, etc.), make sure the surface is sufficiently even
• Carefully remove from the surface all traces of mortar protruding from between the bricks or blocks and fill any gaps in the joints with Mapegrout Fast-Set rapid-hardening, fibre-reinforced cementitious mortar, Mapegrout Thixotropic shrinkage-compensated, fibre-reinforced mortar or Mapegrout T60 if sulphate-resistant mortar is required. As an alternative, use sand/cement mortar admixed with Planicrete latex rubber for cementitious mixes
• Concrete surfaces, on the other hand, must have no uneven areas or gravel clusters. Repair or smooth over any rough areas with the same products from the Mapegrout line mentioned above. Round off all sharp edges on horizontal and vertical surfaces with suitable power tools and blend in the areas between foundations and vertical walls by forming a fillet joint made from the Mapegrout product chosen
• Seal any breaks in correspondence with structural joints with Mapeband TPE bonded to the substrate with Adesilex PG4

Application

• Prime the substrate
• Dilute Plastimul with approximately 45-50% of water and mix until completely blended
• Apply the primer by brush, roller or spray
• Alternatively, prime the surface with Plastimul C diluted 1:10 with water, as indicated in the relative Technical Data Sheet
• Then apply Plastimul in two layers, as follows:
  • First coat: When the primer is completely dry, apply a coat of neat Plastimul at least 1.5 mm thick (wet thickness) with a trowel, brush or by spray
  • Second coat: Spread on a coat of neat Plastimul at least 1.5 mm thick (wet thickness) with a trowel or by spray. Please note that, to achieve performance levels in compliance with EN 15814 standards, at least two coats of product must be applied with a final dry thickness of at least 3 mm.
• When filling the foundation trenches or applying successive protection layers, Plastimul must be dry. The drying time varies according to weather conditions, surrounding temperature, level of humidity, wind, the thickness applied and the type of substrate
• Before filling in protect the waterproofed surfaces with suitable protective drainage layers
• Only use suitable material for filling in excavated trenches, that is, well assorted material without stones against the protective drainage compacted into a series of layers 40 to 50 cm thick
• Consumption: Approximately 0.5 kg/m² of diluted product, when used as a primer. Approximately 1.7 kg/m² per mm of thickness of dry product for a seamless film applied on a flat surface. Consumption is higher if applied on uneven substrates. Please note that, to achieve performance levels in compliance with EN 15814 standards, two coats of product must be applied in the thickness indicated in the standards.
• Tools can be cleaned with water while Plastimul is still fresh. When hardened, it can only be removed mechanically

Limitations

• Do not apply Plastimul if the temperature is lower than +5°C or on freezing surfaces or if the temperature is higher than +30°C.
• Do not apply Plastimul if it is about to rain
• Do not dilute Plastimul with organic solvents
• Do not apply Plastimul on the surface of containers used for storing edible products
• Do not use Plastimul to waterproof structures in contact with organic solvents or mineral, vegetable or animal fats
• Do not use Plastimul to waterproof structures exposed to UV rays
• Do not use Plastimul to waterproof structures with water under pressure
• Apply a protective drainage layer to protect Plastimul before infilling
